A Multidisciplinary Approach to the Functional and Esthetic Rehabilitation of Amelogenesis Imperfecta and Open Bite Deformity: A Case Report

ABSTRACT The treatment of amelogenesis imperfecta (AI) with an anterior open bite (AOB) is a challenge for the clinician and often requires a multidisciplinary team of specialists. Most often, patients suffering from these conditions are young and a good functional and esthetic long‐term result must be aspired. This clinical report illustrates the orthodontic, maxillofacial, restorative, and prosthodontic rehabilitation of a 20‐year‐old woman with a hypoplastic form of AI and an AOB malocclusion, having received treatment for the last 6 years. It included adhesive resin composite restorations, orthodontical and maxillofacial surgery with a one‐piece Le Fort I osteotomy, and a genioplasty. Subsequent prosthodontic therapy consisted of 28 all‐ceramic crowns whereby a solid interdigitation, a canine guidance, and consistent and regular contacts between tooth crowns could be achieved to assure a good functional and esthetic oral situation. The tooth preparation techniques guaranteed minimally invasive treatment. The patient was affected very positively. CLINICAL SIGNIFICANCE This article describes an interdisciplinary approach to the successful treatment of a patient with a hypoplastic form of amelogenesis imperfecta over a period of 6 years. It starts with a discussion of the conservative steps taken during adolescence and concludes with the final prosthetic rehabilitation with all‐ceramic crowns after reaching adulthood.
